UWL and Using Object Visualization with ABAP WD

Hi all,

In a User Decision step I need to display the Object/Class link that appears as an attachment in UWL using WDA. I have made an entry in the SWFVISU for my Custom Class and method EXECUTE_DEFAULT_METHOD. Performed the Re-Register and Clear Cache in the Portal but do not see an entry for the class in any of the configuration files for the back end system. Re-starting the Portal server has no effect either. (I have also tried with Visualization Type 'NONE - Object Not Represented' with the same result and cannot suppress the link). The issue is same in the DEV and Sandbox environments mentioned below.

SAP EP 7.0 - SP13( DEV), SP16 (Sandbox)

Back End: BASIS/ABA - 700/14(DEV), 700/16 (Sandbox)

I also need to know how to specify/define the Class Key Attribute as a parameter for the visualization rather than WI_ID.
